Fixes in “best network switching” for certain Samsung devices.
For posterity’s sake, on those devices, this code fragment would return the current connection’s level as -200, throwing off the app’s network switching logic
final WifiInfo wi = mWfm.getConnectionInfo(); int currentNetworkLevel = wi.getRssi();
A minor update really…
Fixed compatibility with 802.11AC networks (was showing wrong connection speed).
Fixed issue with notification icon.
Updated translations: Slovak (thanks, Pyler) and Spanish (thanks, Jorge).
Updated Traditional Chinese translations (TW, HK).
I now have a “Unique custom Google+ URL”.
In my circles: 34 people — means they give these URLs to pretty much anyone :)
I’ve been asked several times to implement the oh-so-popular navigation drawer for folder selection in AquaMail, replacing the old-fashioned drop-down list.
The technical part is easy, but the more I get into it, the more it seems like a bad idea. Here is why.
TL;DR – I’m happy for the young energetic designers who are making a career out of “inventing imaginative ways to improve mobile device navigation patterns”, but there are significant drawbacks which may outweigh the claimed benefits.
1 – I’m faced with the decision of whether I should keep the drop-down or not.
Having two entirely different UI elements that do same thing (let the user directly navigate between folders) is strange, putting it mildly.
Let’s look at the options:
- Remove the drop-down entirely and keep just the drawer.
This is bad for users who are not experts on Android UI patterns. Yes, the drawer indicator is there (the three tiny horizontal stripes to the left of the app’s icon), but… Sometimes I get emails asking how to access the menu, and there are users who barely know about the Back button. Nothing wrong with these people, they’re just not experts on technology or UI, and I’d rather not make the app more confusing to them.
- Remove the drop-down, make the folder name (where the drop-down is currently anchored) another way to open and close the drawer. The native Gmail app does this.
The issue is how to make it obvious that this is how things work? The drop-down is easy to see and understand because it has a little triangle bottom right, like all other drop-downs everywhere else.
Keeping the triangle makes the UI immediately inconsistent: it looks like a drop-down, but when tapped, it does something else (opens the side navigation drawer).
Removing the triangle is even worse (the native Gmail does this): now there is no visual clue that this is not just a piece of text, but an active UI element.
This last issue is now very common in Android and becomes more and more common. Personally, as a user, I find it confusing like hell. It used to be that buttons looked like buttons, lists looked like lists, etc. – now UI elements that “do stuff” no longer look like anything, they’re just areas the user is supposed to tap (or slide? which way? or long press?), and the only way to find out is to use mind-reading skills.
2 – The navigation drawer is anatomically wrong.
It forces the thumb to move sideways (left to right) which is awkward in the first place, and then, when it’s almost touching the palm, the thumb has to move vertically to select from the now open navigation drawer’s list.
Really, if you’re reading this, try it yourself and pay attention to how your thumb’s muscles tighten when it’s bent and closest to the index finger. It’s at this point that the navigation drawer requires the thumb to start moving up and down to pick from the list.
Furthermore, a drop-down list can extend the entire width of the screen (or close to it), so the thumb does not have to move left much at all. A navigation drawer, by convention, is anchored on the left, and is more narrow than the screen (the shadow effect). Reaching sideways to the left is hard, especially on large screen devices. Reaching up is easier: the phone can shifted in the hand, up and down; but this does not work for reaching to the left.
3 – The navigation drawer doesn’t achieve what it’s supposed to.
Ostensibly, the motivation (or one of) is better usability on large screen devices, the explanation being that a drop-down anchored in the action bar is difficult to reach.
However, a side drawer also has a list, of same items, and it’s natural to start them at the top (unless you have some UI element that can go first, just to take up space… see the Google+ app, it’s the profile photo).
Let’s see, we wanted to get away from a list that starts near the top, and we ended up with a list that starts near the top, which is not any easier to reach, and which puts additional stress on the thumb’s muscles.
4 – How do other app do it?
My favorite type of question (why isn’t Mr. Obama any good at Judo?)
The native Gmail app sort of manages to make its navigation drawer more usable by moving action bar icons to the top, which in turn pushes the drawer’s activation area (the current folder’s name) to the left.
But at what price?
Android 4.0 introduced a way to put action bar icons along the bottom on “narrow screen devices”, i.e. phones. This is a great feature, making frequently used actions easier to reach (better location; a larger number of icons showing at the same time).
Now Gmail’s way of implementing the drawer puts the icons back at the top. Let’s see, the number of icons is now reduced from 4 or 5 to just 2, the rest require tapping the “three dots” icon or the hardware Menu button. And these two icons are now located — ta-da! — near the top of the screen.
In summary, “one small but very visible step forward, two giant steps back” is what Gmail’s navigation bar treatment seems to me. They made 2 or 3 commands (tasks) less accessible, to improve accessibility of 1 command (task): switching folders.
Will I keep the already-almost-implemented navigation drawer?
Really don’t know yet. Maybe I’ll add a Prada logo instead.
New version just released to Google Play.
- New feature: scan for and switch to best network (among already configured). Disabled by default, please see app settings.
- Fixed EAP (802.11x) networks on Android 4.3.
- Added a setting for “exit” button: disable WiFi or not.
- Fixed “open first” network sorting.
- An option to show detailed WiFi state in a status bar notification, off by default, see app settings.
- High res graphics for Full-HD phones (Samsung S4, HTC One, Sony Z, etc.)
More on the “best network” feature:
- Disabled by default, please enable in settings.
- Switches between already configured networks, will not connect you to some random open WiFi network on its own.
- Triggered by the firmware reporting the current network’s signal level changes, or by time. Do not expect this to be instant.
- By design, only works when the device is not sleeping. If your device does “stuff” in the background, there is a good chance the switching will work, when the device is woken by other apps.
- By design, does not interfere with the device’s automatic (firmware driven) initial connections, i.e. when there is no connection yet. Will switch a bit later if a better network is found.
current signal level at which, or below, to switch (defaults to -65 dBm, which is definitely not a very good connection, but still sort of usable);
min. interval for scans / reconnects, defaults to 5 minutes;
how good a new network’s signal level has to be, compared to the current one, for the switching to happen, defaults to +10 dBm.
Most of my time these days is taken by Aqua Mail.
Fixed compatibility of the one-tap switcher widget with Android 4.1-4.2.
Android bug report filed here: https://code.google.com/p/android/issues/detail?id=43336
Updated Portuguese translation.
Added Portuguese-Brazilian translation.
Added “sticky broadcast” permission which is not needed, but there are firmwares who think it is, and crash the app.
Does any of this ever get any testing?
When’s the final Android release coming out? I’m impressed with the 16 beta versions so far, but would like to see at least a release candidate.
